Component Specifications

Definition
Connector pads are precisely engineered metallic contact surfaces integrated into sensor layers, designed to establish reliable electrical interfaces between sensor elements and external wiring or connectors. These pads serve as termination points for signal transmission, power delivery, and ground connections, ensuring minimal contact resistance and stable electrical performance in industrial sensing applications.
Working Principle
Connector pads function by providing a conductive surface area where electrical contact is made through pressure, soldering, or conductive adhesives. When mated with corresponding connectors or wires, they complete electrical circuits, allowing sensor signals (such as voltage, current, or digital data) to be transmitted to control systems. The pads maintain consistent electrical conductivity while withstanding mechanical stress and environmental exposure.
Materials
Copper alloy (typically C11000 or C19400) with electroplated finishes: gold flash (0.05-0.1μm) over nickel barrier (2-5μm) for corrosion resistance and solderability. Alternative materials include silver-plated copper or conductive polymer composites for specialized applications.
Technical Parameters
  • Pad Size 1.0mm x 1.5mm to 3.0mm x 3.0mm
  • Thickness 0.2mm to 0.8mm
  • Resistance < 10mΩ per pad
  • Peel Strength > 1.5N/mm
  • Current Rating Up to 3A continuous
  • Surface Finish ENIG (Electroless Nickel Immersion Gold)
